A lot of works are set in One Million BC. However, some works just do a few episodes in prehistory, while mostly in other eras. When this happens, they usually have a prehistoric animal be an ancestor of the characters in the show.

However, most writers only know a few types of dinosaur. When they don't think they can pass off any of them as the ancestor of their character, they tend to use either and "Xsaurus", "Saber-toothed X", "Xdactyl", "Xraptor" or "CaveX". May also sometimes occur in modern-day set dramas involving mutated animals.

Funny Animal characters are usually neanderthals unless they are antagonists.

Note that this includes both portmanteaus or mix and match critters of a modern-day animal and a prehistoric animal. May intersect with Artistic License - Paleontology.

    Comic Books 
  • The "Cave Cat" segment of Garfield: His 9 Lives shows Garfield as a saber-toothed housecat and Odie as a giant green saber-toothed dog.


  • After Man: A Zoology of the Future has saber-toothed weasels and monkeyraptors
  • Man After Man: An Anthropology of the Future has saber-toothed humans and ground slothmen.
  • The book "Science Made Stupid", a parody of children's science books, has a Puppisaurus in a sidebar about mammal-like reptiles (the group did exist, albeit as a group of animals increasingly closely related to true mammals, but it didn't include a Puppisaurus).
  • Similar puns fill up the out-of-print children's book, "Dodosaurs: Dinosaurs That Didn't Make It".

    Live Action TV 
  • In Power Rangers Time Force, the Quantum Ranger had a dinosaur mecha called the Quantasaurus Rex, or Q-Rex for short. The Mirai Sentai Timeranger version was simply the V-Rex. Power Rangers Megaforce would later recycle the Q-Rex name for its dino mecha in homage to the original.
  • Power Rangers Dino Thunder called its main mecha combination the Thundersaurus Megazord.
    • One episode also had the Rangers' class at a paleontology dig, and when Kira tried to get Dr. O's attention she claimed that she found a "morphasaurus" fossil.
    • Dino Thunder's counterpart does a similar play on the Japanese word for dinosaur(s), "kyoryu"; calling their dino-like mecha "bakuryu" ("blastosaurs").

    Newpaper Comics 
  • The title panel of this Garfield strip has Odie as a Dogasaurus.

    Video Games 
  • Teenage Mutant Ninja Turtles: Turtles in Time has a reference to this in the prehistoric level, called "Prehistoric Turtlesaurus". No actual tutlesaurus appear, but funny enough, you fight Slash (who kind of looks the part) as a boss in the SNES port.
  • Aerodactyl from Pokémon is a cross between a gargoyle or a wyvern and a pterodactyl.

    Western Animation 
  • The Flintstones sometimes makes vague references to creatures like a "chickensaurus"
  • Scrat from Ice Age is a saber-toothed squirrel. However, he is actually based on Leptictidium.
  • The Future Is Wild features a saber-toothed wolverine, a caracararaptor, and a turtlesaurus (specifically named a snowstalker, carakiller, and toraton).
  • The Looney Tunes short Prehistoric Porky shows Porky to be descended from a cavepig, while Pre-Hysterical Hare shows Bugs to be descended from a saber-toothed rabbit.
  • The Tom and Jerry short "Prehisterics" has Tom as a saber-toothed housecat and Jerry as a cavemouse. During the short they encounter a giant saber-toothed rabbit.
  • The Sponge Bob Square Pants episode "Ugh" has Spongebob, Patrick, and Squidward as a cavesponge, caveoctopus, and cavestarfish, with Gary as a giant snailsaurus.
  • Dino Squad has many examples. Most of the mutated creatures created by Victor Veloci were mutated mixes of modern day and ancient creatures. Only the Dino Squad were 'perfect' creatures.
  • The Phineas and Ferb episode "The Tri-Stone Area" has Perry as a saber-toothed platypus.
  • The catsaurus and catdactyl on Bling-Bling's Island on Johnny Test.
  • The "Terrible Thunderlizards" segment of Eek! The Cat often uses this. Like a porcupinosaurus, for example.

    Real Life 
  • In reality, many prehistoric animals seem like this. For example, ceratopsids (rhinosauruses), sauropods (giraffesauruses), pterosaurs (batsauruses), ichthyosaurs (dolphinsauruses), ornithomimids (ostrichsauruses), spinosaurids (crocodilesauruses), Dinofelis (saber-toothed leopard), etc. Subverted since they aren't ancestors of the similar modern-day creatures.
  • Some prehistoric creatures are named this way (but the X part is almost always in another language), such as Nanuqsaurus (polar bear lizard) and ichthyosaurs (fish lizards). An interesting aversion is Struthiosaurus, which means "ostrich lizard" but looked like this.
